Political parties are inevitable. They are alliances between people with common interests(like chess). They've always existed, and have always been disliked by those who oppose those interests. Which is also inevitable.

Our celebrated "Two Party" system actually includes a lot of other political parties, but we don't call them that. We call them "special interest groups"--the nice thing about the "two party system" is that if your special interest group doesn't get what it wants from one party, it can go to the other.

Political parties are like religions in a lot of ways, not the least of which is that they reflect the weaknesses character flaws of their members. Come to think of it, internet forums are like that, too.
